纵观人类发展史,物理学始终是社会进步的重要力量。如果说18世纪以前,物理学是对一些理论的探索、认识、证明与完善;那么19世纪至20世纪初,物理学则聚力于如何将知识运用于生产、生活实践,如何不断地推动社会与科技的发展。19世纪末至20世纪初,以X射线、放射性、电子的发现为先导,以相对论与量子力学的创立为标志,物理学由经典物理走向了现代物理。第二次世界大战以后,物理学的许多分支学科如雨后春笋,纷纷问世, Throughout the history of human development, physics has always been an important force for social progress. If the eighteenth century, physics was to explore, recognize, prove and perfect some theories. Then from the 19th century to the beginning of the 20th century, physics focused on how to apply knowledge to production and life practice and how to continuously promote the society And the development of science and technology. From the late 19th century to the early 20th century, with the discovery of X-ray, radioactive and electronic as the guide, with the creation of the theory of relativity and quantum mechanics as the symbol, physics moved from classical physics to modern physics. After the Second World War, many branch disciplines of physics mushroomed, come out one after another,
